FUNCTION OF THE BRAINSTEM
Midbrain:
•Visual & auditory processing and reflexes
•Fine-tuning of voluntary movements
Pons:
•Relay station for cerebellum
•Control of sub-conscious movement
Medulla Oblongata:
•Control of cardiovascular functions
•Control of respiration
•Control of gastrointestinal functions

GROSS ANATOMY OF CEREBELLUMGROSS ANATOMY OF CEREBELLUM
Location:
 The term cerebellum is from
“Latin meaning” the little brain.
 part of the hindbrain situated in
the posterior cranial fossa.
 behind the Pons and medulla
oblongata, separated from two
structures by the cavity of fourth
ventricle.
 It is covered by tentorium
cerebelli and is connected to
brain stem by three cerebellar
peduncles.
 In adults the weight ratio
between cerebellum and
cerebrum is 1:10,Infants 1:20
13
Consists of two laterally, large
hemisphere which are united by
midline vermis.
Cerebellar surface is divided by
numerous curve transverse
fissures giving it a laminated
appearance
One conspicious fissure
“horizontal fissure" extends around
dorsolateral border of each
hemisphere from middle
Cerebellar peduncle to vallecula,
separating superior and inferior
surface

The deepest fissure in the
vermis is primary fissure,
which curves ventrolaterally
in the superior surface of the
cerebellum to meet
horizontal fissure.
Primary fissure divides the
cerebellum into anterior and
posterior lobe.

Arbor vitae cerebelliArbor vitae
•In Latin “ tree of life” it is
the white matter of the
cerebellum.
•It is so called because of
the tree like appearance.
•It brings sensory and
motor sensation to
and from cerebellum.

Archi-cerebellum
posterior lobe
(Vestibular part)
•It is
formed of the flocculo-nodular
lobe + associated Fastigial
nuclei, lying on inf. Surface in
front of postero-lateral fissure.
•Embryo logically, it is the
oldest part of cerebellum.
•It receives afferent Fibres.
From vestibular apparatus of
internal ear Via vestibulo-
cerebellar tracts.
•It is concerned with
equilibrium
Neocerebellum
Archicerebellum
Paleocerebellum
21
Paleo-cerebellum (spinal
part) •it is
formed of midline vermis +
surrounding paravermis +
globose & emboliform nuclei.
•It receives afferent
proprioceptive impulses from
Ms.& tendons Via
spinocerebellar tracts (dorsal
& ventral) mainly.
•it sends efferent to red
nucleus of midbrain.
•it is concerned with muscle
tone & posture.
Paleocerebellum
22
Neo-cerebellum
(cerebralpart)
•It is the remaining largest
part of cerebellum.
•It includes the most 2-
cerebellar hemispheres +
dendate nuclei.
•It receives afferent impulses
from the cerebral cortex +
Pons Via cerebroponto-
cerebellar pathway.
•it sends efferent to Ventro
lateral nucleus of thalamus.
•it controls voluntary
movements (muscle

INTERNAL STRUCTURE:-INTERNAL STRUCTURE:-
 Cerebellum consists of
outer layer of grey matter
known as cortex and
inner layer of white matter
known as medulla.
 The medullary core is
composed of incoming
and outgoing fibres
projecting to and from the
Cerebellar cortex.
 Medullary core also
contain the nucleuses of
the cerebellum which are
four in number.

White matter of the cerebellum
 Consists of three types of nerve fibres in the
white matter
A.Axons of purkinje cells
The only axons to leave Cerebellar cortex to end
in deep
Cerebellar nuclei specially dendate nucleus.
B.Mossy fibres
They end in the granular layer.
C.Climbing fibres
They end in the molecular layer 31
The internal circuity of cerebellum:-
 Don't leave the cerebellum, interconnect
different regions of cerebellum.
 Some connect the same side.
 Some connect the two Cerebellar hemisphere
The Cerebellar efferent via middle Cerebellar
peduncle(MCP) and inferior Cerebellar peduncle
(ICP)
The Cerebellar afferent via superior Cerebellar
peduncle(SCP) and from Fastigial from inferior

FUNCTION OF THE BRAINSTEM Midbrain: •Visual & auditory processing and reflexes •Fine-tuning of voluntary movements Pons: •Relay station for cerebellum •Control of sub-conscious movement Medulla Oblongata: •Control of cardiovascular functions •Control of respiration •Control of gastrointestinal functions 11
  • 13. GROSS ANATOMY OF CEREBELLUMGROSS ANATOMY OF CEREBELLUM Location:  The term cerebellum is from “Latin meaning” the little brain.  part of the hindbrain situated in the posterior cranial fossa.  behind the Pons and medulla oblongata, separated from two structures by the cavity of fourth ventricle.  It is covered by tentorium cerebelli and is connected to brain stem by three cerebellar peduncles.  In adults the weight ratio between cerebellum and cerebrum is 1:10,Infants 1:20 13
  • 14. Consists of two laterally, large hemisphere which are united by midline vermis. Cerebellar surface is divided by numerous curve transverse fissures giving it a laminated appearance One conspicious fissure “horizontal fissure" extends around dorsolateral border of each hemisphere from middle Cerebellar peduncle to vallecula, separating superior and inferior surface Horizontal fissure Vermi s Hemisphere Superior surface Anatomy of cerebellum......contd. 14
  • 15. The deepest fissure in the vermis is primary fissure, which curves ventrolaterally in the superior surface of the cerebellum to meet horizontal fissure. Primary fissure divides the cerebellum into anterior and posterior lobe. Primary fissure Anterior lobe Posterior lobe Primary fissure External surface of cerebellum 15
  • 17. Fourth ventricle Arbor vitae cerebelliArbor vitae •In Latin “ tree of life” it is the white matter of the cerebellum. •It is so called because of the tree like appearance. •It brings sensory and motor sensation to and from cerebellum. 17

From vestibular apparatus of internal ear Via vestibulo- cerebellar tracts. •It is concerned with equilibrium Neocerebellum Archicerebellum Paleocerebellum 21
  • 22. Paleo-cerebellum (spinal part) •it is formed of midline vermis + surrounding paravermis + globose & emboliform nuclei. •It receives afferent proprioceptive impulses from Ms.& tendons Via spinocerebellar tracts (dorsal & ventral) mainly. •it sends efferent to red nucleus of midbrain. •it is concerned with muscle tone & posture. Paleocerebellum 22
  • 23. Neo-cerebellum (cerebralpart) •It is the remaining largest part of cerebellum. •It includes the most 2- cerebellar hemispheres + dendate nuclei. •It receives afferent impulses from the cerebral cortex + Pons Via cerebroponto- cerebellar pathway. •it sends efferent to Ventro lateral nucleus of thalamus. •it controls voluntary movements (muscle Neocerebellum 23

INTERNAL STRUCTURE:-INTERNAL STRUCTURE:-  Cerebellum consists of outer layer of grey matter known as cortex and inner layer of white matter known as medulla.  The medullary core is composed of incoming and outgoing fibres projecting to and from the Cerebellar cortex.  Medullary core also contain the nucleuses of the cerebellum which are four in number. 27

B.Mossy fibres They end in the granular layer. C.Climbing fibres They end in the molecular layer 31
